© When operation of the controller requires jogging (inching) or plug stopping or when normal operation requires continued operation in excess of 5
operations per minute or 10 operations in a 10-minute period, the plugging or jogging horsepower ratings must be followed.
® In lieu of a 500 to 1500 VA control transformer, a 50 VA unit in conjunction with a control relay can be used as follows:
1. Wire control relay coil in control circuit on secondary side of control transformer.
2. Wire two poles of control relay in series with contactor coil at line voltage.
Mounting Position
Devices must be mounted to a sturdy vertical surface with the line
side terminals up. No other orientations are permitted.
Operating Temperature
Equipment is designed for ambient temperature outside of
equipment enclosures to be -25° to 40°C. When contactor is
energized, temperatures will be above outside ambient in
equipment enclosures. Temperature rises inside the enclosures
should be limited so that internal air temperature does not exceed
65° for sizes 00 to 6 and 60°C for sizes 7 to 9. If condensing
moisture is present, space heater kits should be used to prevent
condensation when contactor is not energized.
Storage temperature should be -30° to 65°C. If equipment is
stored over 1 week, it may be necessary to cover the equipment
and provide a source of heat to prevent condensation.

Short-Circuit Ratings
Control Transformers
Fusible forms of combination magnetic starters equipped with UL
labeled, nonrenewable, NEC-type fuses listed in the table below,
are adequate for installation on motor branch circuits where the
available short-circuit current at the incoming line terminals of the
starter does not exceed the value shown.
Circuit breaker-type combination magnetic starters equipped with
the circuit breakers listed in the table at right are adequate for
installation on motor branch circuits where the available shortcircuit current at the incoming line terminals of the starter does not
exceed the value shown.
For either type, it is recognized that maintenance of some
components may be required after a branch circuit fault and in
some cases a device may require replacement.
Where to Use
It is often desirable to use a control transformer in conjunction with
a magnetic starter or controller to provide low voltage control.

GE's full voltage (600-Volt maximum) magnetic motor starter has
an encapsulated coil and a 3-leg overload relay to protect against
overloads in all phases. It is on standard specifications of major
manufacturers. The line offers features and benefits most asked
for by users.
Forms available include reversing and nonreversing, two-speed,
and combination, sizes 00-9.
• Toolless contactor disassembly (Sizes 00-4)—allows
quick access for inspection and maintenance. Just release two
retainers and pull a clip to get at magnet, coil, and contacts.

GE's magnetic motor starters listed here may be used for starting
full-voltage, nonreversing, single-speed ac motors up tp 1600
horsepower, 600 Volts maximum, providing protection to the
motor against running or stalled overloads.
Their compact size and ease of wiring make them especially
suitable for motor control centers, custom-type control panels,
and switchgear equipment. Refer to page 1-4 for features of basic

Typical Schematic Diagram for CR306 Starter
(NEMA Sizes 00-6)
Ordering Directions
1. Specify starter by complete Catalog Number.
Example: CR306C103 is a Size 1 starter with 230-240-Volt,
60-Hertz coil and in Type 1 general-purpose enclosure @
$246.00, GO-10G.
2. The final letter of the Catalog Number denotes extra auxiliary
contacts (sometimes referred to as auxiliary interlocks). Order
the desired extra auxiliary contacts by replacing the final letter
with one from first column of auxiliary interlock table (see page
1-58).
Example: CR306C103AAB is Size 1 starter with one extra
normally open, auxiliary contact @ $312.00, GO-10G.
3. Starter forms are available with coils of other ratings than those
shown on pages 1-6 to 1-7. Refer to coil suffix table, page 1-3
for information. To order forms with other coil ratings, insert
suffix from coil table in place of fifth and sixth numbers of
listed starter Catalog Number shown on pages 1-6 to 1-7.
Example: A CR306C102 NEMA Size 1, three-pole starter in
Type 1 enclosure with 24-Volt, 60-Hertz coil becomes a
CR306C124 Catalog Number.
4. For continuous rated motors with a service factor of 1.15 to 1.25
select the heater with maximum motor Amperes equal to or
immediately greater than the actual full-load current taken
directly from the nameplate of motor. Order heaters by
complete Catalog Number from appropriate heater tables on
pages 1-71 to 1-75. List Price $9.00 each, GO-10H. Packaged
in quantities of three; must be ordered in multiples of three.
